WINDOW-SCREEN.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed November 9, 1906. Serial No. 342,710.

To (LZZ whom it may concern.-

Be it known that we, ARTHUR GILBERT TIDD and SAMUEL COOK, citizens of the United States of America, and residents of Northampton, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in lVindow-Screens, of which the following is a full, clear, and exact description.

This invention relates to improvements in a window screen and in the parts provided as appurtenances of the window easing with which the screen is engaged, and by which it is guided in its movements for closing, or leaving more or less open, the window open ing.

The objects of the invention are to provide means for most easily, conveniently, and quickly placing the screen in its place, and removing it from the window, to so construct the novel parts that they are adapted to properly fit or engage in window casings which may have variations from given dimensions, corresponding to which the screens are approximately made; and generally to simplify, and cheapen the operable parts comprised in the novel devices.

The improvements constituting the present invention are hereinafter delinitel described in conjunction with the accompanying d awing, and set forth in the claims.

In the drawings,Figure 1 is a perspective view showing the portion of a window casing with window sashes raised therein, and showing the screen as in a position preparatory to being engaged for vertically sliding movements within the window casing. Fig. 2 is a horizontal sectional view through an intermediate part of the screen and through the adjacent side portion of the window casing. Fig. 3 is substantially a vertical sectional view as taken 011 line 33; Fig. 2. The sec tion line 2+2, on Fig. 3 definitely indicates the horizontal plane on which the section, Fig. 2, is taken. Fig. 4 is a perspective view of one of the outwardly reacting and inwardly yielding springs with which the screen frame is provided, showing a preferred specific structural formation thereof; and Fig. 5 is a perspective view showing, on a larger scale, an improved and preferred formation of the side strips or trackways provided vertically at opposite portions of the window casing.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings,A represents the win dow casing in which the sashes B are provided as usual.

C represents the screen frame.

The window casing has vertical grooves, or is preferably provided with vertically connected metallic strips in which said grooves are formed,-at its opposite sides and properly offset from the plane of the sashes and the screen frame is constructed with comparatively shallow longitudinal recesses l) b within its opposite vertical edges, and has springs D formed from sheet steel or other thin metal located in said recesses, each spring having an end portion thereof secured by a screw 0 or otherwise to the screen frame; and each spring has an outwardly deflected portion (Z adapted to yield inwardly, and to react in the reverse direction, which outwardly curved or deflected portion (Z is provided with an outwardly projecting provided for acquiring a detachable engagement in the aforementioned vertical track like groove at the adjacent side of the window casing. The said spring, moreover, is constructed with an aperture 9 through its free extremity and an adjusting screw h is provided for each spring, its shank being passed loosely through the said aperture 9, with a screw thread engagement into the screen frame while its head has a limiting relation against the outer face of the end portion of the spring, as clearly shown in the drawings.

A very practical and comparatively valuable appurtenance of the window casing consists in vertical thin metallic strips m for the opposite sides of the window casing, formations of which constitute the aforementioned vertical track-like grooves with which the screen is engaged by means of the springs D provided to the screen and having the outwardly reacting and inwardly yielding bosses for acquiring snap-catch engagements in said grooves; and the said strip of thin metal just referred to is made with separate vertical parallel ribs 10, 10, constituted by longitudinal corrugations of the strip, producing boss f therebetween the move a; and it, moreover, has a longitudina ly continuous right angularly bent portion or section 12, preferably constituted by a double thickness -of the metal, as shown in Fig. 5, to have the disposition relatively to the outer face of the screen represented in Figs. 1 and 2 of the drawings.

The screen frame has recesses 7', shown in Fig. 1, within its opposite vertical edge portions, a boundary of each being constituted by the oblique shoulder 15, extended from the upper (or it might be the lower) end of the screen to the outer face thereof.

The aforementioned metallic strips :20 are fastened vertically in place oppositely within the window casing by small nails or like attachment means.

To place a screen in its proper engagement within the window casing to slide up and down on a plane parallel with the sashes, one of the window sashes is moved open, and the screen is brought in an oblique position, as indicated in Fig. 1, so that its shoulders 15, 15, have rests or limiting engagements against the right angular flange like portions 12, and then by swinging the screen frame on the fulcrums constituted by the said shoulders 15 toward, and finally to, the vertical position, the spring carried bossesf at upper and lower edgewise portions of the screen frame are snapped into engagement in the grooves a between the corrugations 10, 10 of.

the casing strips. The screen may now be easily slid vertically from its closed position, and as easily returned to its closed position, as occasion may require.

It will be appreciated that considerable difficulty might beeXperienced in engaging or disengaging the screen within or from the window casing were the right angular flange like rests 12 and the recesses having the oblique shoulders 15 not provided, for it is not practicable to twist the screen frame to bring it to its place in the casing; and the snap-catch actions of the spring bosses are automatically caused in the action of swing ing the screen frame from an oblique position, in which one end of the frame is located at the plane coincident with the opposite grooves c a, to its ultimate and proper vertical position.

It will also be perceived that the right angular flange like vertically continuous rests or portions 12 of the metallic track groove strips ocby overlapping beyond the edge of the screen frame at the outer face of the latter, serve as guards against the entrance of air, moisture or dust between the edges of the screen frame and the window casing, a consideration when the appliance is used as a weather screen or storm window.

It is preferred that the recesses j j, having the oblique shoulders 15, be provided at the I upper end of the screen frame.

While in this specification for uniformity 'wardl reactin ortion havin b 22 the frame C is referred to as a screen frame, such term is not to be understood as limited to a foraminous screen, for it is mtended to apply as well to a weather screen or storm 7 window.

The vertical grooved strips so as, may have their locations on the window casing either inside or outside of the window sashes, as in various cases may be most desirable or possible of application, the screen being, of course, correspondingly located.

We claim 1. The combination with vertically grooved guiding parts provided at opposite sides of a window casing, of a screen frame having recesses within its opposite vertical edges, sheet metal springs located in said. recesses each havin a portion thereof connected to the screen name, and a yielding and outa boss, formed by an indentation in the spring, for acquiring a detachable snap-catch engagement in the groove of one of said guiding parts of the window casing.

2. The combination with frame guiding parts provided at opposite sides of the window casing, each consisting of a flat strip of thin metal having separated vertical parallel ribs formed by outward displacement of the metal from which said strip is constituted along separated longitudinal lines thereof, producing a continuous intermediate tracklike groove, of a frame having in the opposite vertical edges thereof sheet metal springs having bosses for acquiring detachable snap catch engagements in the grooves in said frame guiding parts at the sides of the casmg. I

S. The combination with. frame guiding parts provided at opposite sides of the window casing, each consisting of a sheet strip of thin metal having separated vertical parallel ribs formed by outward displacement of the metal from which said strip is constituted along separated longitudinal lines thereof, producing a continuous intermediate tracklike groove, and each said strip having a vertically continuous portion outside of said groove forming ribs bent at right angles to the plane of contact of the strip on the window casing, of a frame having in the opposite vertical edges thereof sheet metal springs having bosses for acquiring detachable snap catch engagements in the grooves in said frame guiding parts at the sides of the casing.

e. The combination with a frame having in the opposite vertical edges thereof outwardly reacting, and yielding, engagement members, and having at opposite edges, at an end portion thereof rearwardly opening recesses, one boundary of each being constituted by a shoulder oblique to the face of the frame, of frame guiding parts provided at opposite sides of the window casing, each IIO e an

comprising a vertical longitudinally continuous, track groove, in which said members detachably engage, and a vertical member outwardly beyond said groove; arranged parallel with the plane of, and extended partially across, the window casing opening, said ver tical members serving as rests for said sh oulders in the action ol. placing the frame in its engagement in the casing.

5. The combination with screen frame guiding parts for provision at opposite sides of a window casing, each consisting of a flat strip of thin metal having separate vertical parallel ribs constituted by longitudinal corrugations of the strip, producing a trackway groove between said ribs, and each strip hav- :ing a longitudinally continuous right angular member at its outer portion, of a screen frame having recesses within its opposite vertical edges and having at opposite edges at an end portion thereof recesses, a boundary of each being constituted by a shoulder oblique to the face of the frame, sheet metal springs located in said recesses, each having'an end portion thereof secured to the screen frame and having an outwardly deflected and yieldingly reacting portion provided with an outwardly projecting boss and having an aperture in its free end portion and a screw for each spring having its shank passed loosely through the said aperture and with the thread engagement into the screen frame, and having its head in limiting relation to the free end portion of the spring.
